NOTE 6: The filter gain outside of the pass band is measured with respect to the gain at 1020 Hz. The input signal is the digital equivalent of a
sine wave (digital full scale = 0 dB). The nominal differential DAC channel output with this input condition is 6 VI(PP). The pass band
is 0 to 3600 Hz for an 8-kHz sample rate. This pass band scales linearly with the conversion rate.
